Patented July 4, 1911.

Application filed August 10, 1910. Serial No. 576,538.

To all whom it may concern. I

Be it known that I, JnssE LINES, a citizen of the United States, residing at Sabetha, in the county of Nemaha and State of Kan sas, have invented new and useful Improvements in Seed-Bag Filling and Sealing Machines, of which the following is a specification.

The present invention appertains tomaehinery for filling fiat packets, such as small paper bags, with seed or other commodity in measured quantity,'pasting the flaps of the bags, folding and sealing the flaps and finally removing the packets from the machine and delivering the packets at a predetermined point of discharge.

The machine embodies a feedin mecha-' nism of unique structure for supplying the material-in regulated quantity to be filled into the'paelu-ts or flat containers such as paper bags having sealing flaps, said feeding mecharusm comprising a hopper to receive the material in bulk and a distributor to operate in the hopper to effect discharge of the predetermined amount of material therefrom at eachoperation, the delivery I mechanism being adjustable to admit of varying the quantity delivered at each operation, and spouts leading from the hopper to direct the material to theproper points of discharge to he received in the packets or containers.

The invention further contemplates holders which receive the material from the spouts of the feeding mechanism and direct that they may pass to a position for the next step in the operation, namely, to have paste or lil' adhesive applied to the sealing flap. The-hagholders and the cooperating gripping nie hanisn'i involve a novel structure, the parts being of such formation and arrangement as to insurc'positive action and efl'ieiemcy in operation, while at the same time enabling the parts to be gotten ateasily for adjustment or replacement when necessary. The bag holders embody a funnel and a bag entering portion, the latter comprising two parts which are normally closed so as to retain the material until said portion enters the bag when the parts open to admit of the material discharging. .The bag gripping member comprises a yieldable portion, which by preference is arranged to coopcrate with the movable art of'the bag entering portion of the ho] or. The ejector operates through the holder and between the members of the bag entering portion and incidental to serving as means for positively detaching the bag from the holder italso serves to prevent any of the material remaining in the holder, since the movement of the ejector therethrough agitates any material remaining therein and insures discharge thereof, with the result that each packet or container receives the full amount of material designed to be supplied thereto.

The invention further contemplates a pasting mechanism of peculiar structure and combined tli'erewit-h are means for arresting movement of the bags or containers after the same have been filled and detached from the bag holders, said mechanism besides arresting the filled bags further serving to move the bags to bring their sealing flaps into the path of the paste distributer to insure the application of a sullicient quantity of paste or like adhesive to the sealing flaps for securing them when folded and pressed upon the body ofthe bags. The pasting mechanism embodies a box or receptacle for holding a quantity of paste, a distributor for taking up a quantity of the paste and a brush for receiving the paste from the distributor and-applying the same to the sealing laps of the bags. Combined with the pasting and bag arresting mechanisms are means for imparting the necessary movements thereto in accordance with the spirit of the invention to insure a harmonious accssary movement is prevented and a machine produced having a maximum capacity of output.

A further purpose of the invention 15 the provision of devices for folding the flaps of the l'iags or containers after paste has been applied thereto andfor sealing such flaps when folded, the-sealing mechanism embodying means for setting or drying the paste by utilizing heat, the latter being applied in the form of a heated presser member, which while pressing the sealing flap into final position also sets the paste or ,5 adhesive by being heated. The sealing I mechanism embodies means for folding the sealing fiaps and means for pressing such flaps.when folded and at the same time applying heat to theisealing flaps to prevent 1 their loosening upon release of the bags from the compressive force of the'sealing means. The machine further embodies delivery mechanism for removing the sealed packets, bags or containers from the sealing mecha- 1 nism and delivering the same to a predetermined point of discharge, the deliverymechanism being positive in operation and embodying gripping means for taking hold of the packets and carrying them to a given 0 point and releasing their hold, thereby permitting the packets to automatically drop clear of the machine,

In connection with the several mechas nisms herein referred to as forming adjunctive parts of the machine as a whole it may be stated that the invention further extends to the devices associated with the working parts and forming elements thereof and which are referred to in detail in the following description, illustrated in the accompanying drawings and pointed out at length in the appended claims.

It is to be understood that the drawings illustrate the preferred embodiment'of the invention, but that various changes maybe resorted to in adapting the invention for certain needs without departing from the spirit of the invention. 9 v In the drawings: Figure 1 is a front view of a machine for filling and sealing packets embodying the invention.

Fig. 2 1 is a detail of the several trip arms, which are concentrically mounted and adapted to operate the several parts connected with the pasting and delivery mechanisms.

Corresponding and like parts are referred,

to in the following description, and indicated in all the views of the drawings, by the same reference characters.

The working parts of the machine are mounted upon a. suitable framework embodying front posts 1, rear posts 2 and suitable connecting bars 3 and 4, the bars 3 extending transversely of the machine and the bars 4 runmng longitudinally and connecting the uprights 1 and 2. The main shaft 5 1S adapted to receive the power for driving the machine and is provided with a fly wheel (3 and a clutch 7, the latter being of any type to admit of throwing the machine into or out of operation when the shaft 5 is in motion, the shipping being effected by means of a hand lever 8. A transverse shaft 9 mounted near the upper rear portion of the framework is provided at one end with a. pulley, which is connected by means of a drive belt 10 with a pulley secured upon the main shaft 5. A gear wheel 11 is securedt to the opposite end portion of the shaft 9 and meshes with a gear wheel 12 secured to an end portion of a shaft 12-5 mounted upon the upper portion of the framework and paralleling the shaft 9. The gear wheel 12 meshes with a gear whcel'let secured to an end portion of a shaft 15 mounted upon the upper portion of the fran'iework and paralleling the shafts 9 and 13. A pinion 1G, in mesh with the gear wheel 12, transmits power therefrom to a gear wheel 17 secured to one end of a transverse shaft 18, which is mounted upon 1 'ackets or extensions forming part of the framework. The gear wheel 17 has a .crown. gear 19 upon its outer side which meshes with a bevel pinion 20 sccurtul to the upper end of a shaft 21, which inclines slightly to the )er )endicular and provided at its lower end with a bevel pinion 22, which meshes with a companion bevel pinion 24 secured to one end of a transverse shaft 25 to which the paste brushes 26 are secured. The shaft 18 has arms 27 secured thereto which are adapted to operate the ejector mechanism which detaches the bags or containers from the holders after the material has been supplied thereto.

The feeding mechanism forsupplying the material to the bags or containers in 1neasured quantity comprises a hopper 28, which is approxin'iately of cylindrical form and arranged approximately concentric with the shaft 15, said hopper having its front portion open, as indicated at 52!). A series of spouts 2E0 lead'rearwm'dly and downwardly from the upper portion of the hopper and direct the material to the bags or containers, it being understood that a. spout is had for each bag holder. The spouts $10 merge into ahead, which connects with the upper rear portion of the hopper 28. Arms 31 are se cured to the shaft 15 and rotate therewith and support a shaft32 at their outer ends, said shaft having a crank 33 at one end, wlnch is adapted to engage a stop 34. near the upper rear portion of the hopper 28, so

or forward ends with the followers 44.

nieasnres or cups 3.) are attached to the inner ends of the supports 36 and project forwardly therefrom so as to pass through the material and scoop up the same in the forward movement of the arms 31. hen the cups 3!; reach a point opposite the head or upper ends of the spouts 30 the crank 33 comes in contact with the stop 34 and is tripped thereby to cause the shaft 32 to make approximately a one-half rm'olution, whereby the cups are caused to assume a rearward position, as indicated most clearly by the dotted lines in Fig. 3, with the result that the material contained therein is discharged in the spouts 30 and directed thereby to the bags or containers. \Vhen the crank 33 clears the stop 3 11 the spring 37, which has been stretched by the turning of the shaft 32, contracts and returns the supports 36 and the cups to normal position. This operation takes place the instant the c and: 3?, clears the stopi-ld and at the upper portion of the hopper where there is no material. to impede or interfere with the return of the cups to a given position. The capacit y of the cups or measures is regulable to admit of controlling the amount of material to be supplied to the packets. For this purpose a set screw 3%,) is threaded into each of the supports 36 and is provided at its inner end with a. plate 40, which constitutes a falsebottom for the cup or measure and which may be moved to a greater or less distance from the bottom of the cup to ltgll' late the space for receiving the material.

The magazine for receiving the bags 01' containers to be filled is iiulicated at ill and comprises a bottom and sides, the bottom. being provided atv its inner or delivery end with a stop 4-2 which arrests the forward nuivement of the bags or containers 43. A follower -14- opcrates in the magazine and supports the pile of bags or containers 4-3 and is pressed forward by means of a spring 45, which is attached at one end to the fran'icwork and at its opposite end to an arm 46, which is pivoted at 7 to an extension of the framework. An arm 46 is ocated at each side of the machine and the two arms are connected at their lower ends by means of a bar to which rods -l-9 are attached, said rods connecting at. their inner spring 50 is mounted upon eachof the rods magazines. A bar 55 extends from one side ing mechanisms.

piece 53 to the other cross the magazines and is provided with detents 56 for engaging with the flaps of the bags or containers to hold them from pressing forward too far so that the front portion of the bag in position to be next filled may stand open, as indicated most clearly in Fig. 11, with the result that the bill or enterlng portion of the bag holder may readily pass into the bag preliminary to discharging the material therein. The detent 56 consists of a spring having a horizontal portion to extend over the sealing flaps of the bags and a pendent portion to project in front of the foremost flap of the series to limit their movement forward when the bag to be filled next is in proper position for receiving the entering portion of the bag holder. The pendent portion of the detent 56 is approximately in vertical line with the stop 42, the twoserving to arrest the forwardmovement of the bags and to properly position the foremost bag of the pile so that it may receive the entering portion of the bag holder when the latter is lowered to deliver the next charge of material to the bag or container. The chute 57 inclines forwardly and down wardly from the delivery end of the magazine. The bags or containers when filled along the chute 57 to the pasting and seal- It is to be understood that a chute 57 is had for each magazine and constitutes a runway for the packets,-each.

of the chutes comprising a bottom and retaining side pieces. v

Each of the bag holders comprises a fun- ,nel 58 arranged to receive the material from a spout and a bag entering portion comprising members 59 and 60L The bag entering portionis sha ed like a bill so as to readily pass into the liiags or containers, the entering end being slenderand tapered. -The member 59 is fixed, whereas the member 60.

' is pivoted and secured to a transverse shaft 61, which is mounted in bearings applied to a transverse bar 62 which is provided at its ends with uprights 63. The bag holders are mounted to receive both a vertical and a lateral movement, the vertical movement causing the bill portions to enterand leave the bags, whereas the lateral movement serves to remove the filled bag from the magazine to ,clear the stop 42 and the pendent portion of the detent 56. The bag holders are mounted upon the transverse bar 62 and are movable therewith both vertically and laterally, the members 60 having an independent pivotal movement. The transverse bar 62 is moved vertically by means of eccentrics 64 secured to the shaft 9 and rods 65 connecting straps fitted upon the eccentrics to the uprights 63. The up?- rights 63 are provided with pins 66 and 6 which are arranged to operate in slots. formed in guides 68 secured to the inner.

sides of the rear posts 2. Each of the guide plates 68 has an upper slot 69 comprising an upper vertical portion and a. lower inclined portion, 1 said slots having their members arranged relatively at an obtuse angle. The

'lower slots are formed at the four sides of a switch 70 and comprise vertical portions 71 and 72 and inclined portions 73 and 74. The slots 7 2 extend above'the upper ends of the inclined slots 73 a distance to receive the pins 67 so as to clear the upper ends of the switches 70, as indicated most clearly in Fig. '7. The slots 71 extend below the inclined slots 74 a d stance to admit of the pins 67 clearing the lower ends of=the switch 70, as indicated most clearly in Fig. 8. A crosspiece 75 is securedto each guide 68 and supports a shaft 76 to which the switch 70 is secured. The shaft 76 has an arm 77' at its inner end, to which a spring 78 is attached, said spring being normally under tension and having its upper end secured to the posts 2, so as to hold the switch 70 normally in the position indicated in Figs; 7 and 9. The vertical portion of the' slots 69 corresponds to-the length of the vertical slots 72 and the inclined portion of the slots 69 corresponds to the length of the inclined slots 73 or 74. "When the bag holders are moved downward the pins 66 and 67 travel in the slots 69 and-72 and 74 and during the first part of their downward movement the bag holders move in a vertical plane and during the remainder of their movement the bag holders move forwardly and downwardly, thereby opening the bags and moving the upper portion thereof forward, as indicated most clearly in Fig. 13. When the pins 67 are traveling through the inclined slots 74 the lower ends of the switches 70 are pressed forward and the instant the pins 67 clear the lower extremities of the automatic in action, being pressed forward at .their lower ends by the pins 67 against the tension of the springs 78 and again returned to normal position by said springs 78.

A bag gripper is had for each bag holder and is secured to a shaft 79, which is mounted in bearings applied to the transverse bar 62. Each of the bag grippers comprises two members 80 and 81, the members 80 being fastened to the shaft 7 9, whereas the members 81 are loose upon said shaft. The upper ends of the members 81. are forked so as to embrace opposite ends of the sleeve portions of the member 80 through which the shaft 79 passes and the lower ends of the members 81 project below the members 80 so as to come in contact with the sides of the movable members 60 of the bag holders so as to grip and retain the bags in place there: on. Pins 82 pass through openings formed in the members 80 and 81. and their outer ends'receive springs 83 by means of which the members 81 are held pressed against the members 80. This arrangement admits of the members 81 having a movement independently of the members 80 so as to follow the movements of the bag holders or the movable members 60 thereof. This is. indicated most clearly in Fig. 13, which shows the members 80 and 81 separated at their lower ends. The bag grippers are operated by a turning of the shaft 79, which is offected automatically by the following means: An arm 84 is secured at one end to the shaft 79 and is adapted to engagea stop 85 when the bagholders are at the limit of their downward movement so as to turn the shaft 79 and throw the lower ends of the'bag grippers into engagement with the bag holders. After the grippers have taken hold of the bags in position to be filled they'are locked in operative position by means of a catch 86, which is pivoted to the adjacent upright 63, said catch engaging an arm 87 fastened to the shaft 79 and preferably forming a part of the arm 84. A spring 88 normally exerts an upward pull upon the outer end of the catch 86 so as to cause the stop thereof to engage with the lower end of the arm 87 when the same is pressed rearward by contact of the arm 84 with the stop 85. The spring 88 is connected at its upper end to a bracket or support secured to the adjacent upright 63. A spring 89 is socured at one end to the arm 84 and at its opposite end to the upright 63 to which the catch 86 is pivoted, said spring normally tending to pull the free end of the arm 84 downward so as to carry the bag grippers away from the bag holders. As the bag holders reach the limit of their downward movement the arm 84 is pressed upward by coming in contact with the stop 85, thereby increasing the tension of the spring 89. A- stop 90 secured to the post 2 is adapted to engage the forward end of the catch 86 upon 'ing thebags carried thereby.

the u ward movementof the bag holders and t iereby depress said catch and release the arm 87, thereby admitting of the spring 89 coming into play and moving the shaft 7 9 so as to throw the bag grippers outward and away from the bag holders and releas- The bag holders move upward a distance before releasing the hags, thereby removing the bags wholly from the magazine. The for-* ward movement of the bag holders at the limit of their downward movement serves to open the bags and also to bring the forward end of the catch 86 into the path of the stop 90, whereby the catch is tripped as the bag holders ascend, thereby releasing the bags at the proper time.

Rods 91 are arranged to operate through the bag holders and constitute ejectors for detaching the bags from the holders when filled. The rods 91 are mounted in guide bars 92 and 93, which extend transversely of the machine, .the bar 92 being pivotally mounted, whereas the bar 93 is supported inguides 94 and is movable forwardly and backwardly so as to follow the n'iovements of the ejectors. A bar 95 receives the upper ends of the ejectors, the latter being adjustably secured thereto by suitable fastening means, such as set screws 96. A spring 97 exerts an upward pull upon .a bar 98 through which the ejectors pass and to which they are secured, said spring being attached at its upper end to a bracket 91.) forming a part of the framework. An arm 100 is secured to the bar 95 and is provided with a roller arranged to be engaged by the arm 27, whereby theejectors are depressed at the proper time so as to detach the bags from the holders, which operation occurs a moment after the bagsare released from the grippers. The ejectors are depressed by the arm 27 and are elevated by the spring 97.

The jaws or members 59 and 60 forming parts of the bill or bag entering portion of the holders are normally held closed during the lowering of the bag holders and the entrance of their bills into the bags by means of spring action. As shown an arm 101 is secured to an end'portion of the shaft 61 and projects therefrom in an approximate horizontal direction and is connected by means of a spring 102 with an arm 103 extended from an upright 63. An arm 104 projects in an upright direction from the shaft 61 and pivotally supports a catch 105, which is acted upon by means of a spring 106 to draw its forward or active end downward, said spring being secured at its lower end to a bracket 107 attached to the transverse bars 62 The bracket 107 extends above the bar 62 and is adapted to engage the shoulder or stop of the catch 105 so as to hold the movable members 60 of the bag holders when thrown into open position to admit of the material discharging into the bags. A stop 108 is adapted to engage the arm 101 and elevate the outer end thereof and turnthe shaft 61 so as to open the members 60 and atthe same time throw the upper end of the arm10t forward and carry the catch 105 therewith, whereby the rear end of the catch is disengaged from a stop consisting of spring plates.

109, both stops 108 and 109 being attached to the adjacent post 2. \Vhen the bag holders reach, a given point in their upward movement the rear end of the catch 105 engages with the stop 109, with the result that the forward end of the catch 105 is raised and disengaged from the stop 107, thereby permitting the spring 102 to operate to turn the shaft 61 and close the members of the bag holders. I

The chute 57 is provided intermediate of its upperand lower ends with a movable portion 110, which is mounted upon a transverse shaft 111. The movable portions 110 normally come flush with the bottom of the respective chutes to admit of the packets or filled bags passing thereover. An arm 112 is secured to an end portion of the shaft 111 and is adapted to be depressed at its upper end to cause the shaft 111 to turn and to throw the upper ends of the movable portions110 forward. A spring 113 normally exerts a pulling force upon the arm 112 to draw the salne rearward and hold the movable parts 110 of the chutes in closed position. An arm 11-t is secured to a shaft 115 and isadapted to engage the arm 112 toeffeet a forward movement of the parts 110. An arm 116, secured to the shaft 115, is connected by means of a rod 117 with a crank arm 118 secured to the shaft 9. The parts are so timed that. when a packet 43 reaches the part 110 and is held thereon the shaft 115 is rocked to. throw the parts 110 forwardly and elevate the packets, as indicated most clearly in Fig. 22, to admit of the sealing flaps having paste applied thereto. The packets are pasted in their descent upon the chutes and retained in position upon the parts 110 by means of retarders 110 which are attached to a shaft 120. said retarders An arm 121. secured to the shaft 120. is normally drawn downward at its outer end by means of a spring 122 and extends across the path of a lateral extension at the outer end of an arm 123, which is secured to a shaft 12-t which is adapted to be operated from the shaft 13 by means of a co111iectiotr125, which is attached at its upper end to a .crank arm 126 attached to the shaft 13 and at its lower end to an arm 127 fastened to the shaft 124. The retarders 119 occupy the position shown most clearly in Fig. 2. that is with their lower ends touching the lower portions of the parts 110 so as to arrest the filled bags in their movement over the chutes. After the packets have reached the position indicated in Fig. 2 the shaft 115 has a rocking movement imparted't-hereto, which brings the arm 114 in contact with the arm 112, thereby throwing the upper ends of the parts 110 forwardly, as indicated in Fig. 22, to bring thesealing flaps in position to receive paste from the brushes 26, after which the shaft 115 is rocked backward, thereby releasing the arm 112 and admitting of the spring 113 returning the parts 110 to normal position when the arm 121 is thrown upward at its outer end by contact of the arm 123 therewith, with the result that the shaft 120 is turned to throw the lower ends of the retarders 119 away from the parts 110 and the packets 43 being released again move forward upon the chutes to the sealing mechanism.

The paste brushes 26 are revolved, with the shaft 25 in the manner stated, the parts being so timed that when the packets are thrown forward by the parts 110 their sealing flaps have paste applied thereto. The

brushes 26 are supplied with paste by means of brushes 128 which are attached to a shaft 129, which is arranged transversely of the machine and mounted in suitable bearing, said shaft being rotated from the shaft 15 by means of a sprocket chain 130 passing around sprocket wheels applied to the respective shafts 15 and 129. The brushes 128 act as distributing means to supply paste to the brushes 26 and in turn receive paste from a roller 131, which is arranged to operate in a box or receptacle 132 containing a quantity of paste. The roller 131 is slowly rotated by means of a ratchet mechanism consisting of a ratchet wheel 133 fastened to an end of the roller and an arm 13t loosely mounted upon a journal of the roller 131 and provided with a spring actuated dog 135 adapted to engage with the teeth of. theratchet wheel 133. A rod 136 connects the arm 134: with a side member of a frame 137. which is mounted upon a shaft 138. The frame 137 is oscillated and imparts a corresponding movement to the arm 134, which, through the ratchet mechanism, imparts an intermittent rotary movement to the paste distributing roller 131. The brushes 128 receive a supply of paste from the roller 131 and act as feeders for the brushes 26.

The sealing mechanism is located at the lower end of the chute 57 and comprises means for folding the sealing flaps and pressing the same. upon the body of the bags or containers. At the lower end of the chute 57 is located a rest 139 having a stop 140 atits lower 'end to arrest the descent of the packet 43 after the same has been pasted. The rest 130 has its upper portion spaced from the bottom of the chute and -of the framework.

through this space operates a sealing head 140, which folds the sealing flap of the bag and presses the same upon the packet. The sealing head is heated so as to set or partially dry the paste or adhesive and thereby prevent opening of the flap after thesame has been pressed upon the packet and relieved of the pressure of the sealing head. A burner 141 is located beneath the sealing head and is supplied with fuel from a tank 142, which is located near the top of the machine so as to supply fuel to the burner by gravity feed. The burner 141 may be of any type, such as commonly employed for consuming oil. The sealing head 140 is pivoted at 143 and has an oscillatory movement imparted thereto. An arm 144 extends rearwardly and downwardly from the sealing head and is connected by means of a rod 145 with an arm 146 secured to an end portion of the shaft 115. The rod 145 plays loosely through the arm 146 and a spring 147 mounted on the rod 145 is confined between the arm 146 and a stop or set collar 14S adjustable upon the outer end of the rod 145. When the shaft 115 turns to the left the lower end of the arm 146 is moved rearward, thereby exerting an upward and a rearward pull upon the rod 145, with theresult that the sealing head 140 is moved forward through the space formed between the bottom of the chute 57 and the upper end of the rest 139, thereby completing the fold of the sealing flap and pressing the same upon the packet. A presser head 149 is arranged to exert a downward pressure upon the body of the packet to force the same close upon the rest 139, such operation serving to initially fold the sealing flap of the packet, as indicated most clearly in Fig. 19. The

packet when it reaches the lower end of the chute occupies the position indicated in Fig. 18, after which the presser head 149 is moved downward to bring the packet in close contact with the rest 139, the sealing flap of the packet being partly folded and subsequently completely folded and sealed by the action of the sealing head 1.40, as indicated in Fig. 20. Arms 150 and 151 connect the presser head with a shaft 152, which is mounted in bearings near the lower end The arms 150 and 151 are pivotally connected at 153 and are arranged to break joint in an upward direction, thereby drawing the presser head forwardly, which is essential to clear thes-ealing flap during the operation of the sealing head. The presser head 149 remains in contact with the packet during its forward movement, which latter is sufficient to clear the sealing flap of the packet when closing thereon. The presser head 149 is of L-form in cross section, the horizontaljflange constituting the presser .member and the vertical flange receiving the supporting means.

Pins 154 project from the presser head and are slidably mounted in sleeves 155 formed at the upper ends of vertical. extensions of a cross head 156, which is secured to one end of an arm 157, which is attached to a supplementary arm 158 loose upon the shaft 152, the two arms 157 and 158 being bolted or otherwise connected. Springs 159 are mounted upon the pins 154 and are confined between the sleeves 155 and adjustable stops upon the pins 154. The springs 159 serve to move the presser heads 149 toward the cross heads 156 when the joints between the arms 150 and 151are broken. The arms 151 are pivotally connected to the presser heads 149, this result being accomplished by bars 160, which are secured to the presser heads and have their end portions offset and made rounding to provide journals, which pass through openings formed in-the ends of the arms 151. When the arms 150 and 151 are in line the presser heads 149 are moved downward from the cross heads 156 so as to engage the packets near their open ends, but

.whenthe sealing flaps are folded the presser heads 149 are moved away from the open ends of the packets a distance to clear the sealing flaps and admit of their folding and sealing. The arms 150' are loosely mounted upon the shaft 152 and have extensions 161 at their lower forward ends which project upwardly and receive pins 162 upon which are mounted springs 163. The pins 162 pass through a cross bar 164, which is supported at its ends by arms 165 loosely mounted upon the shaft 152. The springs 163 are confined between the cross bar 164 and adjustable stops upon the pins 162 and when the cross bar 164 is thrown toward the chute bring the presser heads 149 and the cross' heads 156 in contact with the rests 139. The presser and cross heads are held elevated or away from the rests 139 by the action of the arm 167 engaging the-arm 166. One of the arms 165 has an extension 169, which is pro vided at its outer end with an eye 170 through which a rod 171 passes,said rod being loosely mounted upon the shaft 124 and having an adjustable stop 172 for limiting the movement of the extension 169 and the presser and cross heads when thrown away from the rests 139 by the action of the arm 167 upon the arm 166. A series of aru'is 173 are fastened to the shaft 152 to turn therewith and the arms 158 have the end furcated so as to embrace the hubs of the arms 173. Pins 174, supported bythe arms 173, pass loosely through Openingsformed in the arms 157 and support springs 175, which are confined between the arms 157 and adjustable stops on the upper ends of the pins 174. It will thus be understood that there is a yieldalole connection between the arms 173 and 157, hence provision is had for a continued movement of the shaft 152 and the arms 173 after movement of the arms 157 has been arrested by engagement of the cross heads 156 with the packets 43, such arrangement providing for variation in the bulk of the packets. An arm 176 projects from one of the arms 165 and has a limited running connection with a bar 177, which is pivotally connected to an arm 178 secured to the shaft 115. At the proper time, that is immediately prior to the operation of the sealing head, the connecting bar 177 is operated to exert a rearward pull upon the arm 176, thereby turning the arms 165 and movingthe cross bar 164 connected therewith and breaking the joint between the arms 150 and 151, whereby the prcsser head 149 is rawn forward out of the way of the sealing heads and the sealing flaps so as not to interfere with-the proper sealing of the packets. c

The delivery mechanism comprises the frame 137, which is approximately of U-form comprising side members and a lower-herizontal member, the side members being secured to the shaft 138 to turn therewith. Jaws 178 and 179 are located at the lower end of the frame and are adapted to grip the packets and remove them from the rests 139 40 of the sealing mechanism and carry said packets to the'required point of discharge. The jaws 17 8 are relatively fixed, whereas the jaws 179 are movable,'being mounted upon a rod 180 supported in lugs attached to the jaws 178. A cross bar 181 is secured to one end of a forked lever, which is loosely mounted upon the rod 180, said forked lever having an upright "extension 182 adaptedto be engaged by an arm 183 pivoted at 184 to a shaft mounted in the side members .of the swinging frame 137. Pins 184 are connected with the cross bar 181 and pass loosely through the pivoted jaws .179 and receive springs 185, which are mounted thereon and confined between the jaws 179 and adjustable stops of said pins 184. The jaws 179 are closed by means of the forked lever when the upper end of the extension pressed downward its outer end engages a depression 186 formed in the arm 182, thereby holding the arm 183 depressed and the jaws 179 in closed position. A shaft 187 is mounted in the side members of the frame 137 and is provided with arms 188 and 189, the arm 188 being connected by'means of a rod 190 with the arm 183 and the arm 189 having. an eye through which a rod 191 passes, said rod having stops 192 and 193, which are adapted to engage the eye carried by the arm 189 so as to operate the shaft 187 and the arm 183 at the proper time. A spring 194 connects the arm 188 with a convenient point of the machine to normally exert an upward pull upon the arm 188 so as to withdraw the arm 183 from engagement with the arm 182 when the arm 189 is tripped by the action of the stop 192. The rod 191 is connected to an arm 195, which is secured to the shaft 124 to turn therewith. The shaft 124 is adapted to be rocked by means of an arm 196, which is connected by means of a rod 197 with an arm 198 secured to an end portion of the shaft 15, the' rod 197 having its upper end slotted or otherwise constructed to makerunning connection with the arm 198 so as to allow for a limited play. The frame 137' carrying the delivery mechanism is swung toward and away fromthe sealing mechanism by a rocking movement of the shaft 138, which is actuated by means of an arm 199 fastened thereto and connected by means of a bar .200 with an arm 201 fastened to the shaft 15.

In the operation of the machine the seed or other material to be placed upon the market in packages is supplied in bulk to the hopper 28 and is delivered therefrom intermittently in predetermined quantities corresponding to the amount to be placed in each bag or container. \Vhen the machine is in operation the shaft 15 is continuously rotated in a direction contrariwise to the direction of travel of the hands of a clock, thereby causing the feeder to move upwardly upon the right hand side of the hopper and when the shaft 32 reaches a position to bring the measures35 opposite the upper ends of the spouts 30 said shaft is rocked by means of the stop 33 coming in contact with the stop 34, thereby tilting the measures so as to deposit the seed or other material into the spouts 30. The material is directed by the spouts 30 into the funnels 58 of the and a moment thereafter the bags are released and detached from the holders and slide downward upon the chutes 57 and are arrested in their descent in proper position in the manner stated to admit of the sealing flaps receiving paste, after which the bags are again released and move downward upon the chutes until again arrested in position opposite the sealing mechanism, when the flaps are folded and sealed. The delivery mechanism at this stage of the operation comes into play in the manner stated and removes the packages from the sealing mechanism and carries the packages to the required pointof discharge, thereby completing the operation.
